Soldiers assigned to an engineer regiment under the PLA Xinjiang Military Command deploy the Rapidly Emplaced Bridge System (REBS) during a bridge-building training exercise at the foot of the Tianshan Mountains on February 3, 2021. The vehicle-mounted REB is 23-meter long. Under the extreme cold conditions of minus 18 degrees Celsius, it took only 10 minutes for the troops to complete the bridging operation.
